I agree, NIB should mean the original box is included. On some of the boxes, there is information that you may want to know. Serial number to insure that it is the same ball or as a reference if the ball is lost or stolen and if the ball is a first or Blem. I have read where some sellers are selling seconds/blems as firsts so it should be easy to see on the box if that info was removed. Plus, if you have more than just a handful of bowling balls, it is a lot easier to find the ball if you are storing them in the original boxes.
